If someone needs to retreat from these naturally protected adventure routes then they can leave gear in place.

A crowbar isn't necessary.

To remove stainless carrots, use a 12 inch plumber's (Stillson) wrench with a tube extension and turn anti-clockwise. You'll break the glue bond quite easily and you can then unscrew.

To remove recessed ring bolts, use a hammer and chisel to carefully chip away enough of the surrounding rock (not much required) to allow the ring to rotate. Now use a bar through the hole, or the wrench mentioned above, to rotate and extract the bolt.

To remove U-bolts, cut through the steel at the top of the U with a hacksaw. Now turn each shaft with the wrench to break the glue bond and twist out.
